Abstract

Accelerated life testing (ALT) is used to get information quickly on life distributions. This study describes an accelerated life testing for fighter-bomber wheel hubs that is representative of actual service conditions. The acceleration models are proposed based on the fatigue life tests of 2014 aluminum alloy, which is extensively used to make fighter-bomber wheel hubs. The BLUE (best linear unbiased estimation) and MLE (maximum likelihood estimation) are adopted in the estimation of the acceleration models, and the acceleration models under the conditions of different SCF (stress concentration factor) are compared by statistical method to determine the sensitivity of SCF to the acceleration factor of the fighter-bomber wheel hubs made by 2014Al.
